The 22kW charger of the smart ED3 is known for its first series breaking sooner or later. Too bad, because the NLG664 from Brusa is basically a very good charger. It is compact, quiet and very efficient, so perfect for our little speedster.

I just took a closer look at a broken NLG664 and disassembled it. You can find the full post on my website:

Here it is discussed what exactly breaks, how you can exchange it and whether the exchange makes sense.
A workshop in Stuttgart, Germany offers now replacing the 22kW charger with a used one from the 2. generation for only 3.500 €. You can also get just a 2. gen 22kW charger on it's own for 2.500 €: More about that

I know, that the 22kW charger wasn't sold outside of Europa, but this forum is also being used by a lot of english speaking people outside of America.

Exceedingly few Smart ED's were sold in the UK and only a fraction of them with the 22kw charger. US and Canada only have 120-240 single-phase for household electricity so only the 3.3 kw charger is there. The ED was not sold at all in Australia, New Zealand, and all of English-speaking Africa.

So I's say that maybe a dozen native English speakers (in the UK) will ever have to deal with the 22KW charger.

Luckily people in other countries speak English as well. I am from The Netherlands and my 22kW charger failed a few months ago. Exactly the problem as described. I decided to convert my car to the standard 3,3kW charger, but the article was very useful.

Due to the 451 post (Introduction to Service for the Smart electric) being locked out of any replies, I am creating this post.
I was hoping someone might know of a link or pdf of similar information, but for the later 453 (2017-2019 USA) model???

Reset the maintenance reminder on both of my Smarts on the first try today. That's really a first. I think I know the secret, but will I remember it the next time? I think the key is quickly pushing the button in Step 2.
